TOP ROLLS.

SPECIFICATION forming part of Letters Patent No. 333,600, dated January 5, 1886.

Application filed February 28, 1884. Serial No. 122,345. (No model.)

To all whom it may concern.-

Be it known that we, NORMAN H. CHENEY and JAMES F. BoYLEN, citizens of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have in vented a new and useful Saddle for Top Rolls, of which the following is a specification, reference being had to the accompanying drawings.

Our invention relates to saddles for top rolls of spinning frames, mules, 80c; and it consists in the novel construction and combination of parts, substantially as hereinafter described and claimed.

Figure 1 is a vertical crosssectional view of a portion of a spinning-frame having shellrolls,showing the arbors in cross-section and the saddles in longitudinal section. Fig. 2 is a vertical longitudinal sectional view of one of the arbors provided with two of the shellrolls. Fig. 3 is a bottom view of the back saddle. Fig. 4 is a top view of a section of the spinning-frame, showing the shell-rolls on one end of the arbors. Fig. 5 is a view in perspective of the front saddle, and Fig. 6 is a detail view of the stirrup for holding the saddles in place on the arbors.

Referring by letter to the accompanying drawings, a designates a section of the spinning frame or mule, which in all essential particulars is constructed as those now in use, our improvements relating exclusively to the arbors, saddles, and mechanism for holding the saddles in place. The arbors d d d are similar in construction, being cylindrical in crosssection, slightly tapering at their ends, which rest in the bearings in the finger-bar e, and having an enlarged middle portion, 6, which is also cylindrical in cross-section, except the portion at the exact middle of the arbor,which extends upwardly in rectangular shape, and has a plane top, 6 just about on a line with the periphery of the cylindrical portion 6'. The oil-cups f are formed in the exact middle portion of the arbor, and small, very small, oil-passages g 9 lead from the bottoms of the oil-cups f longitudinally of the arbors atabout their axial lines, and then curve downwardly and lead out of the arbors into the shells h, as shown, so that the interior peripheries of the shells are supplied with oil from the oil-cups through these oil-passages. The oil-passages g g are formed by boring axially the required distance in the arbors, closing the ends where the bore commences with plugs d, and tapping the oil-passages at d (1 The back saddle, i, is provided near its ends with nipples 11 i projecting from its under face, and these nipples z" 1", when the saddle is in place, are seated, one in the oil-cup of the back arbor, and the other, 6 in the oil-cup of the intermediate arbor, and prevent said arbors from turning in their bearings. The bores of the nipples t" i are countersunk in the upper face of the saddle Z, the lower one having a groove, Z extending from the rib-seat i to its countersink, to enable the operator to properly seat the drip-rib It on the under face of the front saddle, Z. The front saddle, Z, is provided near its upper end with a perforation, Z having a shallow cup, Z at its top, which leads through the drip-rib it near, its front end, and the oil that is supplied to the shallow cup Z drips from the front end of the drip-rib 70 into the countersink i of the saddle 13, and passes to the intermediate arbor. This front saddle, Z, is provided, j ust above its oil-cup Z, with a crossnotch, m, in which the lower edge of the upper cross-bar of the stirrup m rests when in place. The lower end of the front saddle, Z, curves downward in enlarged form, as at n, and has a plane lower face, n, from which its nipple 12. projects, and is seated when in place in the oil-cup f of the front arbor. The nipples all fit snugly in their seats. The lower end of the stirrup m is provided with an eye, 1), which engages a hook, p, the stem of which passes down through the inclined roller-beam q, and is provided with nut r and a collar, .9, between which a coil-spring,t, operates to regulate the tension of the stirrup on the saddles during the operation of the machine by reason of the fact that the collar 8 slides loosely upon the stem of the hook p. The ordinary Weight may be used instead of' the spring. By this construction either or all of the arbors may be oiled at any time without stopping the machine. The nipples serve to steady the sad dles and keep them in place, and as the arbors cannot turn in their bearings the oilways are kept in line. By slightly modifying the saddles they can be used with these arbors for the front set of rolls, or for the front and middle set of rolls, while the remaining rolls may be of any other pattern. They may be also adapted to the requirements of mules, speeders, railway-heads, or,in fact, any place where top rolls are used. The oilway in the arbor is only one sixteenth of an inch in diameter, so that there is plenty of stock for strength.

The saddles are made of cast-iron; but they may be made of wood, if used on the old style of top rolls or back rolls.

The device is cheap, simple, and efficient for the purposes for Which it is intended, and is not likely to get out of order, while it provides for a savingin time not heretofore attainable in oiling the top rolls of spinningframes and the like.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination, with the arbors having oil-cups, oil-passages, and axial bores, of the front saddle provided with countersunk nipples and drip-rib, and the back saddle having the perforated rib-seat, and the lower nipples secured upon the arbors, and the springactuated stirrup for connecting the saddles, substantially as specified.

2. The combination, with the arbors having axial bores closed at the ends, oil-cups, and discharge-openings, of the back saddle provided with nipples on its under surface seated in the oil-cups of the back and intermediate arbors, and a drip-seat on its upper surface located between the nipples, the front saddle having a perforated drip-rib seated on the drip-seat of the back saddle, and at the other lower end with a nipple seated in the oil-cup of the lower arbor, and aspringactuated stirrup seated on the front saddle for connecting the said saddles, substantially as described.

3. The combination, with the arbors having axial oil-passages closed at the ends, oil-cups, and discharge-openings, of the back saddle having perforated nipples seated in the oilcups of the back and intermediate arbors and a drip-seat on its upper surface, the front saddle having a perforated drip-rib on its lower face seated on the dripseat of the back saddle, and having a nipple, n, and the stirrup for holding the saddles in position, substantially as described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
